Question

我正在使用eclipes创建一个Android卡游戏。由于某种原因，当我调用动画时，我的应用程序崩溃了。我必须做的一个改变是在Flip类中，那就是将layoutview更改为imageview，因为在动画方法中“createDisplayNextView”出错了。

////////ANIMATION
    private ImageView FrontView;
    private ImageView BackView;
    private boolean isFirstImage = true;
private void applyRotation(float start, float end) {
    // Find the center of image

    FrontView = (ImageView) findViewById(R.id.imgC1);
    BackView = (ImageView) findViewById(R.drawable.clubs2);
    BackView.setVisibility(View.GONE);

    final float centerX = FrontView.getWidth() / 2.0f;
    final float centerY = FrontView.getHeight() / 2.0f;

    // Create a new 3D rotation with the supplied parameter
    // The animation listener is used to trigger the next animation
    final cardFlip rotation =  new cardFlip(start, end, centerX, centerY);
    rotation.setDuration(500);
    rotation.setFillAfter(true);
    rotation.setInterpolator(new AccelerateInterpolator());
    rotation.setAnimationListener(rotation.createDisplayNextView(isFirstImage, FrontView, BackView));

    if (isFirstImage) {
        FrontView.startAnimation(rotation);
    } else {
        BackView.startAnimation(rotation);
    }
}

这是Flip类：

你可以试试这个..

public class SplashActivity extends Activity {
    // protected boolean _active = true;
    protected int _splashTime = 5000;
    private ImageView imag;
    AnimationDrawable frameAnimation ;


    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.splashactivity);
        imag = (ImageView) findViewById(R.id.splashactivity_imag);

        imag.setBackgroundResource(R.drawable.splash_animation);

             frameAnimation = (AnimationDrawable) imag
                .getBackground();

             Thread splashTread = new Thread() {
                public void run() {
                    try {
                        sleep(_splashTime);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    } finally {
                        Intent intent;
                        intent = new Intent(SplashActivity.this, HomeActivity.class);
                        startActivity(intent);
                        finish();
                    }
                }
            };
            splashTread.start();
        }

    @Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        frameAnimation.start();

    }

}
